To @ZZ `ifi/wm it may concern:

Be it known that T, LUTHER T. VELEN, a citizen of the United States,residing at Washington, District of Columbia, have in-` vented a new anduseful Shock-Forming Apparatus, of which the following is aspecification.

This invention relates to shock-forming apparatus and consists in thenovel construc its parts whereby the said bundles .may be carried froman approximately horizontal position into a vertical position and boundat their upper portions into the form of a shock. O After'this is donethe bundles are placed upon the surface of the ground in the form of ashockwith its corner portions spread that the stalks may cure and alsothat the shock will havev ample foundation upon which to sustain itselfin case of storm or other similar disturbances.

Fig. "9 isa The shock forming apparatus includes a frame 1 which issupported at its rear portion upon anaxle 2. rThe axle 2 is providedwith an intermediate crank portion 3 and an arm 4 is supported upon theportion 3 of the axle 2 and normally occupies a position at an angle of40 to 45 degrees to a horizontal. A bar 5 is pivotally connected at oneend to the arm 4 and at its forward end is connected with a draftappliance (not shown). This is done for the reason that when thesaid-draft appliance is backed or the animals attachedare backed, thebar 5 is moved longitudinally and the arm 4 is turnedthrough an arc ofapproximately 900. This operation is accomplished with the axis of theaxle 2 asa center of movement. This mechanism has been disclosed indetail in my copending application No. 449,330, filed August 19, 1908,and does not constitute, specifically, any part of the presentinvention. Av dividing fork 6 is carried by an arm 7 which in turn isattached to the arm 4 and stalk-receiving'cradles are pivotallysupported at the opposite sides of the fork 6 and are adapted to-receive the stalks in approximately horizontal positions and swing thesame into vertical position, as the said fork is swung from itslowermo'st to its elevated position. `These cradles form no part `oft-hepresent invention but are covered in my Patent No. 981,336, dated January 10, 1911. In addition to the dividing fork 6, an .auxiliarydividing finger 8 is employed, this linger being mounted in themannerhereinafter described, and remaining, in place. along sides of thefork during the movement of the bundles toward shockforming position.The finger further remains in its dividing position long after the forkhas resumed-its normal position, and is not withdrawn until the finalmovement of the machine away from the completed shock. Secured to theaxle 2 is a beveled gear segment 9 which meshes with a beveled pinion 10at the lower end of a vertical'shaft l1.

Extending vertically from: the rear portion of the main frame l'are twovertical bars 12 that preferably are rectangular in transverse section.At the upper-ends of these bars is secured a horizontally disposedrectangular frame 13 and this framework serves as a support for theshocky assembling and tying mechanism.

Arranged upon the end portions of the axle 2 and beyond the sides of theframel l are plates 14 which are adapted to turn with said axle when itis swung. Plates 15 are pivotally mounted behind the rear edges of theplates 14 and are inclined downwardly and are adapted to drag at theirlower edges upon the ground. The said plates 15 serve as spreader boardsand are of the same width as the plates 14 and arranged to receive thebutt ends of a bundle during the movement of the stalks tothe ground;the butt ends will be somewhat divided and separated. For this purposethe ,upper face of the plate 15 is provided with a plurality ofangularly disposed buttend engaging ribs 16 and at the rear edge of theplate are angular recesses 17 which allow the stalks between the ribs todrop to the ground and be held separated as they strike the ground. Inaddition to the ribs an auxiliary finger 18 is secured to the plate 14and is adapted to swing with the same in order to further assistspreading the stalks. As the plates 14 will swing rearward and upwardduring the time that the shock is being passed from the apparatus to thesurface of the ground, while the dividing board or plate 15 remainsrelatively stationary, it becomes necessary to provide an intermediateguide board and for this purpose a plate 19 is pivoted at its front edgeto the rear edge of the plate 14, while the rear edge of the said plate19 rests upon the upper face of the spreader board or plate 15. As theplate 14 swings upward the plate 19 will be carried to a point near thefront of the under plate 15 and will form an inclined plane down whichthe butts of the stalks may travel in the direction of the plate 15. Asthe forward portion of the plate 14 moves in a downward direction whichoccurs during the shocktying operation, the auxiliary plate 19 willslide down to its initial position over the spreader plate 15, but asthis plate is formed of comparatively thin metal, it will simply passunder the stalks which remain on the said plate 15.

Projecting from the rear end of the main frame 1 is a plate 20, theopposite edges of which are provided with a series of openings 21 topermit adjustment of the pivot pins 0f a pair of shock-spreading levers22. The levers extend out from under the opposite edges of the plate ina position at right angles to the plane of the machine, and these leversare so positioned with respect to the ngers 18 that as the forwardplates 14 turn in an upward direction at their forward ends, the stalkswhich have been supported by the fingers 18 will be thrown to the rearof the levers 22, while the stalks upon the forward portions of theplates 14 will slide down the spreader plates 15, as above described infront of the levers22 so that as the unbound shock now stands on theground, its base is divided into four columns which representapproximately corner bundles. The next step in the operation consists inbringing the upper portions of the stalks together and tying the fourcolumns near the top to form a shock. 1When the stalks are brought toupright position, in the manner as indicated, the fork 6 and finger 8divide the upper portions of the stalks from each bther, while the buttends of the stalks are divided into four columns or parts by the plate20 the levers 22 and the fingers 18. Also some of these stalks will beupon the surface of the ground, while others have not yet moved downbelow the lower edge of the spreader plate 15, the more efectually tospread the columns of the stalks as indicated in dotted lines in Fig. 1of the drawings.

On the vertical bars 12 of the rear frame is guided a verticallyadjustable frame 23. This frame carries the mechanism for gathering thebundles of stalks in the forni of a shock, for tying the shock and foreffecting the discharge of the finished shock from the machine. rIheupper portion of the frame is approximately rectangular in form and isprovided with a cross bar 24 and on top of the frame is a plate 25. Theplate and the cross bar are provided with centrally disposed aliningopenings for the passage of a pin 26 having an enlarged lower end thatfits within a correspondingly large portion of the opening in the bar24. To the upper end of this pin is secured an eye 27 from which extendsa cable 28, said cable being guided over a pair of sheaves 29 carried bythe frame 13 and ruiming down to a winding drum 30 mounted on a shaft 31that is carried by brackets 32 on the stationary frame 1. The windingdrum is hollow and contains a spiral spring 33, the outer end of whichis secured to the inner portion of the drum and tends normally to turnthe drum in such direction as to wind up on the cable and thus elevatethe frame 23, it being understood that the frame is adjustablevertically in accordance with the height of the stalks being cut. Theperiphery of the drum is provided with locking notches 34 arranged forthe reception of a locking pawl 35 which serves to hold the drum 30against the action of the spring and maintain the frame 23 in theposition to which it is adjusted.

Mounted loosely on the pin 26 is a master gear 36 through which motionis imparted to the needle, and to the tying mechanism and to a shockembracing arm that assists in the shock-assembling operation. This gearis provided with two arcuate racks 37 and 38, the rack 38 intermeshingwith a mutilated gear 39 that is secured to the upper Aend portion ofthe shaft 11, this shaft receiving motion first in one direction andthen in the opposite direction as the axle 2 is tilted up and down andthe master gear is further provided with a segmental frame 40 carrying asmaller' rack 4l, which imparts movement to knot-tying mechanism in themanner hereinafter described. At the rear end of the frame 23 are twovertically disposed tubular sleeves 42 and 43 both of which are rigidlysecured to and depend from the frame. Mounted on the sleeves are tubularshafts 44 and 45, respectively. rlhe upper ends of the hollow shafts areprovided with laterally extending arms 46 that are connected by a link47 for mutual movement, the arms and links being so related that whenmovement is imparted to the sleeve 44 in one direction, the sleeve 45will be rotated to the same extent, but in the opposite direction. Thesleeve or shaft 44 carries a shock-engaging arm 48 and the shaft 45carries a similar arm 49.

On the lower end of the rigid sleeve 42 is permanently secured a collar50 from which projects an arm 5l that forms one of the bearings for aknetter shaft 52 hereinafter described. Between the collar 50 and thelower end of the sleeve or shaft 44 is arranged a revoluble collar 53,from which projects a radial arm 54, and said arm carries a dependingfinger 55 that is parallel with the axis of the sleeve 42. rlhe shaft orsleeve 44 and the collar 53 are free for independent oscillatorymovement to a limited extent, the excessive movement being prevented bya pin 56 depending from the lower end of the hollow shaft 44 andarranged to engage against the shoulders or walls of an arcuate recess5'? formed in the collar 53. Surrounding the hollow shaft 44 is ahelical torsion spring 58, one end of which engages the arm 48 and theopposite end of which engages the arm 54, thus tending to separate saidarm to an extent greater than approximately an angle of 90o. Thishowever, will be prevented by the engagement of the pin 56 with theshoulder' 59 of the recess 57 and limit the movement of the arm 48,while the arm 54 is engaged and held from further movement by a pawl 6()that is pivoted on a pin 61 extending upward from the arm 51. rlhe pinis stationary and is provided with a diametrically arranged slot at itsupper end for the reception of a straight strip of spring metal G2 whichextends through a diametrically arranged slot formed in the head of apin 63 that is carried by the pawl. rlhe function of this spring striptending to maintain the pawl in a position in the slot is such that thespring will always return the pawl to the central position, no matter inwhich direction the pawl may have been moved. When following out thisconstruc-v tion, it may be observed that the knotter shaft 52 has an arm64 which, when near the completion of its single rotative movement, willengage the end of the spring 62 and will move the pawl 60 to releasedposition, this movement occurring once during the cycle of operation.

rl`he spring 58 will permit the arms 48 and 49 to move rearwardlyslightly in case the arms are subjected to severe strain during thecompression of a large shock. lf the shock is small, however, the bottomspring is of sullicient strength to hold the arms against any rearwardmovement until the shock is ready to be discharged, and when the shockis in readiness for the discharge, the arm 64 of the counter shaft willmove the pawl 60 to released position, so as to allow the arms 48 and 49to move through an arc of 90o and allow the shock to pass from themachine.

Extending through the stationary hollow sleeves 42 and 43 are two hollowshafts 65 and 66, the shaft 66 carrying at its lower end a cord carryingneedle 67 of hoop-like form. rlhe hollow shaft carries a shockeinbracing arm 68 which assists the needle in encircling andcompressing` the shock before the tying of the knot, this arm being muchshorter, however, than the needle. llhe arm 68 is provided with anarcuate bar 69 curved on a line struck from the axis of the sleeve 42and provided at one end with a vertically extending finger 70, whichfinger is arranged to engage against the finger 55 for the purpose ofrestoring the two arms 48 and 49 to normal positions, after the shockhas been deposited upon the ground, this movement occurring during thedownward movement of the forward portions of the plates 14.

ln order that the operation may be made more clear, it may be statedthat after a shock has been tied, the needle, and the arm which assiststhe needle remain in the dotted line positions shown in the drawings,and the arms 48 and 49 remain in a position at a right angle theretountil the plates 14 again start to tilt forward in the formation ofanother shock. Buring this forward movement of the plates 14, the needleand its auxiliary arm swing outward and in so doing the finger 70 of theauxiliary arm engages 'the finger and turns the shock-supporting arms 48and 49 back to normal positions so that they may bein position toreceive the rear portion of a new shock, while the needle and its armremain out of the way.

To the upper end of the shaft G5 is secured an arm 7l that is connectedby a link 'i 2 to a crank pin 73 carried by a gear segment 74 on theupper end of the shaft 66 and this gear segment 74 is arranged tointermesh with the rack 37 during the rotative movement of the latter,the gear segment serving to rotate the shaft through an arc of 180degrees in one direction during the shock compressing and tyingoperation, and

llO

then back through the same arc in readiness for the reception of thestalks to form another shock. The movement of the shaft 66 istransmitted to the shaft so that the auxiliary arm 68 is also operatedin a direction the reverse of that of the needle, the needle and armembracing the side and forward portion of the shock and compressing thesame against the holding arms 48 and 49.

The gear segment 74 carries a peculiar form of stop, that is amodification of the well known Geneva stop. The segment is extendedbeyond the rack beam and is provided with a concaved face 75 that iscurved on an arc struck from the axis of the stationary pin 26 and thisconcaved face is arranged to engage with the smoothperipheral portion ofthe master gear after the rack 37 has moved out of mesh with thesegment, so that the master gear may continue its movement aftercompleting the movement of the segment, for the purpose of subsequentlytransmitting movement to the knotting device, as hereinafter described.

In order to support the forward portion of the shock as well as toassist in discharging the finished shock, a cross bar 76 is employed.This -cross bar has a central portion extending in a direct transverseline across the machine, and its ends are turned ory inclined asindicated at 77 to assist in guiding the shock into place. This bar iscarried by a horizontally disposed bar 78 which is mounted in anelongated slotted guide bar 79 carried by an arm 8O that is bolted tothe frame 28, the bar 78 and the slot in which it is mounted being ofdove-tail form in cross section, in order to prevent displacement. Thisbar 78 will move forward with respect to its guide 79 but its forwardmovement is limited by a pawl 81 that is pivoted in a bracket 82extending from the arm and entering a locking latch 83 in the bar 78.This particular portion of the mechanism comes into play during thefinal discharge of the shock as will be hereinafter explained.

Extending through the hollow shafts 65 and 66 are two shafts 84 and 85to which are secured arms 86, the connection between the shafts and armsbeing preferably made by a set screw so that the arms may revolveadjustably on the shaft. To the outer end of each arm is pivoted asection 87 and to the outer end of the section 87 is pivoted a section88, the two pivots between the sections 86 and 87 and between thesections 87 and 88, being at a right angle to each other, and eachincluding a clamping nut so that the outer ends of the arms 86 may beadjusted both vertically and horizontally as required, the nuts beingloosened and the sections of the arm moved to proper position afterwhich the nuts are firmly screwed in place to hold the sections inposition. These arms 86 curve outward from the shaft and serve inconnection with the arms 48 and 49 to support the stalks as the latterare discharged from the plates 14, some of the stalks falling rearwardagainst the arms 86 and remaining in that position, until the needle andits auxiliary embracing arm move around to gather the shock together.

To the lower ends of the shafts 84 and 85 are secured additional arms 89which are also made of adjustably connected sections to permit ofhorizontal adjustment, and each of these arms 89 carries a long sleeveor roller 90 that is free to revolve on the arm proper during thedischarge of the shock from the machine, the rollers serving to reducefriction on the arms.

The two arms 89 are brought in a plane to the rear of the plane of thearms 48 and 49 and normally do not come into play when the shock is arelatively small one. If however, the shock is of large size, thecompressing operation will force the arms 48 and 49 to the rear againstthe resilience offered by the spring 58, the spring yielding slightlyand permitting the arms to imove until the shock comes into engagementwith the arms 89, thus automatically enlarging the compression space inaccordance with the size of the shock. The arms 89 have been describedas formed of adjustably connected sections and it is to be understoodthatl under some circumstances these arms may be moved outward to aposition at a right angle to that shown, that is to say, in positionsparallel with the longitudinal axis of the machine, so that they willnot come into contact with the shock under any circumstances. Thismodification of the apparatus, however, is intended more especially foruse where the shocks are delivered unbound and are allowed to fall uponthe ground in the form of bundles to be afterward gathered together andtied in shock form, as more fully described hereinafter. To the upperends of the shafts 84 and 85 are secured beveled gears 90 whichintermesh with beveled gears 91 on a horizontally disposed shaft 92 thatis mounted in a bearing sleeve 93 rigidly secured to the upper plate 25of the frame. Surrounding the shaft 92 is a helical torsion spring 94,one end of which is secured to the shaft, and the opposite end to thebearing sleeve 93. During the outward movement of the arms 89 to permitthe discharge of the shock, the shafts 84 and 85 will be turned and themovement will be transmitted to the shaft 92 thereby placing the spring94 under stress and this spring will thereafter revolve the shaft in theopposite direction and return the arms to the initial position.

The shaft 92 must be normally locked from movement in order to preventthe escape of the shock until the compression and tying operation havebeen properly accomplished, as otherwise the compressing and tying of alarge shock would move the arms to release position, and permit thepremature escape of the shock. To accomplish this the shaft is providedwith a disk 95 having a stop shoulder 96 which engages a pawl 97 that ispivoted on a bracket 98 projecting from the frame 23 and normally heldin operative position by helical tension spring 99. rllhe lower end ofthe pawl is connected by a wire or chain 100 to a bell crank lever 101that is pivoted to the frame 23 and this bell crank lever is connectedto the tail of the pawl 81 by a wire or chain 102, so that if the tailof the pawl is moved down, the movement will be transmitted to the pawl97 and the latter will be moved out of engagement with the shoulder 96of the disk and will be held out of engagement until after the shaft hasbeen turned and the arms moved to open position to allow the dischargeof the shock. After the discharging operation, the retractile force ofthe spring 94 will revolve the shaft 92 in the opposite direction, andrestore the arms 89 to shock-holding position and at this time the pawl97 will be free to again engage with the shoulder 96 of the cam andagain lock the shaft until the completion of the next shocktyingoperation. On the needle is a linger 108 which engages against one of,the arms 89 as the needle moves to open position and thus positivelyreturns the arms 89 to supporting position. The knetter shaft 52 issupported in part by the lower bearing 51 and in part by an upperbearing 104 projecting from the frame 105, and at its lower end thisshaft carries an ordinary form of knotting mechanism (not shown), toco-act with the needle or to operate upon the cord carried by theneedle, in a manner common to binders or other machines of that type. Tothe upper end of the shaft 52 is secured a gear 105l which intermesheswith a gear wheel 106 of the same diameter, the gears making a singlecomplete revolution at each operation, and always stopping at the end ofthe operation with the arm 64 in the position indicated.

y1`he gear 106 is mounted on a shaft 107 which carries a mutilated gear108 that intermeshes with the rack 41. r111e gear 108 carries a ratchetpin or arm 109 that projects beyond the periphery of the wheel andtoward the latter part of the movement is engaged by a pin 110 at theend of the rack, for the purpose of completing a full rotative movementof the gear 108. 1n the operation of this portion of the mechanism, therack 41 is moved and the rst tooth of the mutilated gear engages thefirst too-th of the rack, the mutilated gearwbeing turned until its lasttooth engages the last tooth of the rack, and by this time it has nearlycompleted a revolution. lll`he pin 110 then engages the rigid arm 109 ofthe mutilated gear and carries the latter farther around until thecomplete revolution is effected, and the pin 110 has passed beyond thearm 109 leaving the untoothed portion of the mutilated gear facing therack. The master gear then starts on its return movement, which ocpurswhen the plate l14 is coming to dumping position, without turning thegear and without rotatting the knetter in a backward direction. 1n orderto prevent this backward rotative movement, the shaft 107 carries a disk114 having a stop shoulder 115 with which engages a spring pressed pawl116 so that the shaft and mutilated gear will be positively held. Theoperation of the tilting plate 14, discharging, shock-assembling andtying mechanisms as described contemplates the movement of the arm 4 bythe rearward movement of the draft mechanism, that is to say, by thebacking of the horses and the transmission of this movement to the arm 4through the connecting bar 5. Obviously this movement may be effected bythe use of any other suitable mechanism, if so desired.

The mechanism thus far described operates to assemble the stalks andbind the stalks in the form of a shock, and as a result of theoperations of this mechanism, the upper portion of the shock is embracedby the needle and the auXiliary arm, and is resting against the reararms of the upper frame 28. rlhe butt ends of the stalks are dividedinto four columns two being located at each end of the plate 20 and thetwo at each end o-f the said plate being separated from each other bythe levers 22 as well as the fingers 18, although the latter are aboutto be withdrawn and have no further function. The bundles behind thelevers 22 are resting on the ground, while the bundles in front thereofare still resting wholly or in part on the spreader boards 15.

1t now becomes necessary to eject or discharge the shock from themachine, and to further spread the several bundles or columns so as toinsure the stability of the shock and to provide for ventilation. Theupper portion of the shock is engaged by the transversely extending bar76, this bar being carried by the horizontally guided bar 78 and thesaid bar 78 is provided with the projecting lug 117, said lug having arectangular opening for the passage of a correspondingly shaped bar 118,the lower end of which is bifurcated and is rigidly secured to anejector frame 119.

The ejector frame includes a horizontally disposed bar 120 that isarranged at a point near the longitudinal center of the machine, itsrear end being guided in an opening formed in a bracket 121 projectingfrom the fixed frame 1. From the rear end of this bar depends an arm 122to the lower end of 130 fao which is secured a lower ejector bar 123that is disposed immediately above the plate 20 and is bent forward andthence outward at points beyond the side bars of the main frame 1 toform arms 124 that are disposed normally at the juncture of the plates14 and the spreader plates 15 so that if the ejector frame is movedrearward, or is allowed to remain perfectly stationary, while theremainder of the machine moves forward, the upper portion of the shockwill be engaged by the bar 7 6 and the forward bundles of the shock willbe engaged by the ejector arms 124 and the shock will be positivelyejected from the machine. 1n the operation of'this portion of themechanism, the ejector frame remains perfectly stationary, while theejector bar and arms rest against the forward face of the shock. Theremainder of the machine then moves forward a slight distance andtravels away from the shock, so that the latter being held stationarywill be positively ejected from the machine.

In order to arrive at a clear understanding of the operation of theejector, it is first necessary to consider the mechanism by which theejector is held stationary, while the remainder of the machine travelsfor ward. The ejector frame 119 is provided with a forwardly extendingbar 125 that is guided in any suitable manner, and is dis-1 posed to oneside of the vcentral longitudinal axis of the main frame. To this bar ispivoted an anchor 126, the anchor being mounted at its forward end on apin 127 thatv is carried by a bracket 128 on the bar 125. The downwardlyprojecting spur or cleat 129 of the anchor is arranged to be embedded inthe ground, so that the ejector frame will be held stationary, while theremainder of the machine is free to move forward. Near the upper rearend of the spur or cleat is a shoulder 13() that is arranged to beengaged by a pawl 131 that is carried by a lever 132 pivoted on the arm125, and this pawl is normally held in an engaging position by a spring133. From the upper portion of the pawl projects an operating rod 134which is under the control of the operator, and by pulling this rodforward, the anchor may be released and allowed to move downward andinto engagement with the ground.

The bar 125 carries an upwardly extending bracket 135 having a bearingfor the reception of a shaft 136 and on this shaft is secured a leverhaving two arms 137 and 138. Pivoted to the upper arm 138 is a block 139having an opening for the passage of a curved rod 140, the rear end ofwhich has an enlarged head 141, that is brought into engagement with theblock in order to move the latter forward at times. The forward end ofthe rod 140 is connected to a crank pin carried by a crank 141 on acrank shaft 142 of mechanism 175 driven by a motor 176. During theforward travel of the machine and after the machine stops and the plates14 are tilted and the shock gathered and tied, the shaft 142 makes onecomplete revolution. This results, of course, in a single completerevolution of the crank 141 and the latter moves in the directionindicated by the arrows, the head 141 0f the rod 140 engaging the rear,face of the block 139 and moving the upper end of the lever forwardafter which the crank arm 141 resumes its original position.

Pivoted to the anchor at a point about midway of the ends of the latteris an arm 143 having an elongated slot 144 in its upper portion andthrough this slot extends a pin 145 that projects from the lower arm 137of the lever, this pin being preferably provided with an anti-frictionroller that rides against the walls of the slot. Engaging the lower faceof the anti-friction roller is a washer 146 and between this washer andthe lower washer of the arm is a helical compression spring 147 that isplaced under stress as the lever moves, the spring tending to force thefinger downward, but movement being prevented by the pawl 131 until saidpawl is moved to released position by the pulling strain on theoperating rod 134. 1t will be noted that when the lever is moved to setthe spring, the crank pin 145 is carried to a position to the rear ofthe vertical plane of the axis of the shaft 136 and as the pivotalconnection between the arm 143 and the anchor is in this vertical plane,the parts will be locked and the lever arm 137 will move against a fixedstop lug 148 carried by the bracket 135 so that the spring cannot act toturn the lever and its force becomes effective only when the pawl isreleased, whereupon the spring is expanded and drives the anchor intothe ground, so that the ejector frame will now be held perfectlystationary, while the remaining portion of the machine moves forward andthis movement is permitted without further operative engagement with thespring setting lever, owing to the sliding connection between theoperating rod 140 and the block 139.

Extending between the ejector frame and the fixed lug 149 on the mainframe 1 is a helical tension spring 150 which is placed under stressduring the relative movement of the ejector frame and the main frame ofthe machine, and when the operation of the ejector is complete, thisspring will serve to return the ejector frame to its initial position.

On the main frame of the machine is arranged a vertical arm 151 having alaterally extended finger 152, which as the frame moves forward willengage the lower arm 137 of the spring seated lever and will move thesame forward past its dead center, thereby breaking the lock, or movingthe crank pin 145 forward of the vertical plane of the axis of shaft 136so that the anchor depressing spring 147 is then free to fully expand,and the washer 146 at the upper end of the spring will act on the pin145 and tend to move the spring seating lever back to normal position.This movement is assisted by an auxiliary torsion spring 153 whichsurrounds the pivot pin 127 of the anchor and is connected at one end tothe ejector frame and at the opposite end to the anchor. rllhe torsionspring is much lighter than the anchor depressing spring and is placedunder stress as the latter exercises its force in driving the anchorinto the earth. TWhen, however, the setting lever is drawn beyond thecenter and the anchor depressing spring is no longer retracted, thespring 153 will operate to raise the anchor out of the ground andrestore the same to the initial position, the anchor moving up until itsshoulder 130 is automatically engaged and locked by the pawl 131.

Before the ejector operation is accom` plished and the ejector frameresumes its normal position, there is considerable strain on theejecting mechanism due to the subsequent operation of spreading the baseof the shock, as will hereinafter appear, and to guard against anyfurther rearward movement of the ejector, provision is made for lockingthe same to the fixed frame until the parts are ready for anotheroperation.

@n the fixed frame of the machine is a bar 154, said bar carrying aforwardly projecting arm 155 and this arm carries two pins 156 and 157,the axes of which are in the same horizontal plane. On the pin 156 ispivoted an ejector locking lever 153, the forward end of which is in theform of a pawl and is arranged to engage in a recess 159 in the upperface of the bar 125 of the ejector and the said lever is held in lockingposition by a spring 160 extending between the pin 157 and a second pin161 on the lever, the longitudinal axis of the spring being in a planeabove the axis of the pivot pin 156 so that the locking lever will beautomatically held in locking position. l/Vhen the locking lever ismoved out of engagement with the ejector, the spring passes below theaxis of the pin 156 and thereupon holds the lever in release position.The rear endrof the lever has a shoulder 162 that is arranged to engagea pin 163 on the anchor, and is further provided with a cam 164 that isarranged to be engaged by said pin as the anchor moves upward.

The normal position of the parts after setting t-he spring 147 is thenindicated in the drawing, and when the rod 140 is moved forward and theoperating rod 134 is pulled and th@ anchor released and ydriven into theground, the pin 163 will pull downward on the shoulder 162, thus tiltingthe locking lever and raising its forward end out of engagement with thelocking recess 159,while the spring 160 will thus hold the locking leverin released position. This movement is further assisted by an arm 165that projects from the upper portion of the pawl lever 132 and isbrought into engagement with the rear end of the locking lever as thepawl lever moves to release the anchor, so that the locking lever iscompelled to move to released position. l/Vhen the anchor moves upward,the pin 163 engages the cam surface 164 of the lever, and tends to raisesaid lever up to such position that the axis of the spring 160 will bethrown above the axis of the pin 156 so that the lever will be moveddown to engaging position and the parts will be automatically locked,ready to resist the strain that tends to pull the ejecting mechanismrearward.

1n following out the ejecting operation it will be remembered that thepawl S1 normally rests in the recess 83 of the bar 76 and when the framewhich carries the pawl moves forward, while the ejector bar 7 8 remainsstationary, the pawl rides up outl of the recess and exerts a downwardpull on the wire 102, this movement being transmitted through theconnecting parts to the pawl 97 which releases the dislr 95 and allowsthe shaft 92 to turn for the purpose of permitting the shock-engagingarms 89 to release the rear portion of the shock. At the same time thearms 124 of the ejector remain stationary, while the frame movesforward, and these arms engage the forward bundle columns of the shoclrand hold the same while the machine moves forward, so that these bundleswill be moved from the spreader plate 15 and the base of the shock willthen move down so that all of the column bundles rest on the ground. Theforward movement of the frame will of course, carry the plate 2Oforward, and as a result of this the levers 22 will act to separate theforward bundles of the shock from the rear bundles of the shock, andsubsequently will operate to separate the forward bundles from eachother. rlhe two levers 22 are pivoted to arms 166 that project rearwardfrom the main frame, and the pivot pins 167 of these levers aresurrounded by torsion springs 168 each having one end engaging the arm166, the function of the spring being to restore the levers 22 topositions at right angles to the longitudinal plane of the machine afterthe levers are clear of the shock. rlhe inner arms of the levers areconnected together for mutual movement, one of them having a pin 169 andthe other a slot for the reception of the pin. To the inner arm of onelever is connected a link 170 which extends to a lever 171 that ispivoted on a pin 172 carried by the under side 'of the plate 20, boththe lever and link being provided with a plurality of openings in orderto permit adjustment of the points at which they are pivotallyconnected. That end of the lever 171 opposite the link is provided withan upwardly projecting pin 178 that extends through an arcuate slot 174;arranged on a curved line struck from the axis of the pin 172 and thispin engages a yoke 175 formed in the cross bar 123 of the ejector, andit is through this connection that the strain on the ejector frame istransmitted during the spreading of the base of the shock.

When the parts are in the positions just at the commencement of the,ejecting operation, the levers 22 extend out at right angles to thelongitudinal plane of the machine. The ejector bar then remainsstationary, while the frame moves forward, and during the preliminaryportion of this movement, the levers 22 will still be held 'in theJ'irst mentioned position so as to move the forward column bundles awayfrom the rear bundles. By the time the pin 173 has reached the end ofthe slot 17 4;, the levers 22 will then have swung rearwardly at theirouter ends so that they will brush against the inner sides of theforward column bundles of the shock and spread them further apart, sothat the base of the shock has four widely spaced points of support toinsure its stability and to permit free passage of air therethrough.
